TRANSFORMEDGE Transform an edge with an affine transform.

   EDGE2 = transformEdge(EDGE1, TRANS);
   where EDGE1 has the form [x1 y1 x2 y1], and TRANS is a transformation
   matrix, return the edge transformed with affine transform TRANS. 

   Format of TRANS can be one of :
   [a b]   ,   [a b c] , or [a b c]
   [d e]       [d e f]      [d e f]
                            [0 0 1]

   EDGE2 = transformEdge(EDGES, TRANS); 
   Also wotk when EDGES is a [N*4] array of double. In this case, EDGE2
   has the same size as EDGE.
